iface-location: allow enabling without SIM

Browse Source 
When the modem is in a failed state because of a SIM-related error,
like a missing SIM, or if the modem is SIM-locked, allow the
Location interface to initialize and be enabled anyway.

This allows someone without a SIM to use the GPS, which does not
particularly require a phone subscription. It also allows
someone with a SIM to use the GPS even if the SIM is still
locked.

This patch was reworked, while keeping the original idea, by:
Aleksander Morgado <aleksander@aleksander.es>

Fixes #183

This method may require the client to authenticate itself.
When location signaling is enabled by the user, any client application (including
malicious ones!) would be able to use the #org.freedesktop.ModemManager1.Modem.Location:Location
property to receive location updates. If further security is desired, the
@signal_location argument can be set to %FALSE to disable location
updates via D-Bus signals and require applications to call
authenticated APIs (like <link linkend="gdbus-method-org-freedesktop-ModemManager1-Modem-Location.GetLocation">GetLocation()</link>)
